一、開啟socket

phpinfo();查看是否開啟了socket擴展，否則在php.ini中開啟。

二、服務器端代碼的寫法

<?php error_reporting(E_ALL); set_time_limit(0); //ob_implicit_flush();$address = '127.0.0.1'; $port = 10005; //創(chuàng)建端口 if( ($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) {echo "socket_create() failed :reason:" . socket_strerror(socket_last_error()) . "\n"; } //綁定 if (socket_bind($sock, $address, $port) === false) { echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($sock)) . "\n"; } //監(jiān)聽 if (socket_listen($sock, 5) === false) { echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($sock)) . "\n"; } do { //得到一個鏈接 if (($msgsock = socket_accept($sock)) === false) { echo "socket_accepty() failed :reason:".socket_strerror(socket_last_error($sock)) . "\n"; break; } //welcome 發(fā)送到客戶端 $msg = "<font color='red'>server send:welcome</font><br/>"; socket_write($msgsock, $msg, strlen($msg)); echo 'read client message\n'; $buf = socket_read($msgsock, 8192); $talkback = "received message:$buf\n"; echo $talkback; if (false === socket_write($msgsock, $talkback, strlen($talkback))) { echo "socket_write() failed reason:" . socket_strerror(socket_last_error($sock)) ."\n"; } else { echo 'send success'; } socket_close($msgsock); } while(true); //關閉socket socket_close($sock); ?>

服務器端需要在cli模式是執(zhí)行，有可能cli模式下php.ini文件載入的不一樣

可以像如下輸出

這時候在zhoxh目錄下就有個tem.text文件。查看 Configuration File (php.ini) Path => C:\WINDOWS 。不是我的php.ini 文件，這說明調(diào)用的php.ini文件時錯誤的。這時候我們要指定php.ini文件命令如下

注意的是我的php可以直接執(zhí)行時配置了環(huán)境變量。

三、客戶端

<?php //error_reporting(E_ALL); echo "<h2>tcp/ip connection </h2>\n"; $service_port = 10005; $address = '127.0.0.1';$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); if ($socket === false) {echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n"; } else { echo "OK. \n"; } echo "Attempting to connect to '$address' on port '$service_port'..."; $result = socket_connect($socket, $address, $service_port); if($result === false) { echo "socket_connect() failed.\nReason: ($result) " . socket_strerror(socket_last_error($socket)) . "\n"; } else { echo "OK \n"; } $in = "HEAD / http/1.1\r\n"; $in .= "HOST: localhost \r\n"; $in .= "Connection: close\r\n\r\n"; $out = ""; echo "sending http head request ..."; socket_write($socket, $in, strlen($in)); echo "OK\n"; echo "Reading response:\n\n"; while ($out = socket_read($socket, 8192)) { echo $out; } echo "closeing socket.."; socket_close($socket); echo "ok .\n\n"; ? 執(zhí)行結(jié)果： server:

client:
